Javascript Regex replace [0] and not 0

Question

I would like to replace every instance of [0] in my HTML but the regex I am using now replaces all 0s not just [0]. Here's what I have:

var clone = clone.html().replace(/[0]/g, total); // Total is a number that increments

An example of what I would replace is something like:

<input id="Items[0].Id" name="Items[0].Id" value="0" type="text" />

But the above Javascript replaces the 0 in value="0", any ideas where I am falling through?

Please someone reclose with http://stackoverflow.com/questions/928072/whats-the-regular-expression-that-matches-a-square-bracket — Wiktor Stribiżew, Nov 22 '16 at 08:59

You will need to escape the opening square bracket:

var clone = clone.html().replace(/\[0]/g, total);

If you leave it like that ([0]) it will be treated like a character class consisting of only the character 0.

There is no need to escape the `]` symbol here. – Wiktor Stribiżew Aug 17 '16 at 07:47
@w0lf thanks that seem to have done the trick... – Morgs Aug 17 '16 at 07:59
